Guest's review of Becker Traffic Assist HighSpeed 7934

Bad Points
Once you have a decompress failed error on the unit it will never work properly again.
There is limited assistance from Becker or updates to the software to fix the problem.
Found multiple sites with comments regarding this same problem.

General CommentsI think there is a firmware or software glitch with my Becker sat nav. I purchased a second unit before the problem occurred in the first one.

Now the second one occasionally works (with the "decompression failed" message once in a while), the first unit after being turned on at some point will arrive at the decompress failed message.
